A general localized disturbance was given to an incompressible conducting fluid of infinite extent in a uniform magnetic field, and the final stage of decay was examined for the case in which a net linear momentum was imparted to the fluid. It was found that after a sufficiently long time the velocity field is that due to the superposition of two identical viscous vortex rings, of the type found by Phillips for the corresponding problem in a non- conducting fluid, whose centers move in opposite directions along the uniform magnetic field with the Alfven wave velocity. Some remarks are included about the decay of a turbulent wake behind a body moving through the fluid. (auth)
